Database disclosure via second-order CSV SQLi
Published Aug 16, 2026 · Updated Aug 16, 2026
SQL injection in NEX-Forms 9.2.4 and earlier allows remote authenticated users to read database data via additional_params. The submission_report2 AJAX handler stores that value, and CSV export later incorporates it into an existing SQL query without sufficient escaping or preparation. The handler lacks a nonce check and relies on a capability configurable down to Subscriber, while successful extraction still requires a later CSV export.
